Abstract (en)

[origin: WO9821045A1] An apparatus for continuously providing dampening fluid (20) from a fluid reservoir (16) to a plate cylinder (12) of a lithographic printing press includes a pan roller in contact with the fluid in the reservoir. A transfer roller set includes a transfer roller rotated by friction from the pan roller at a speed proportional to the plate cylinder and a reverse direction transfer roller (30). An ink receptive oscillating roller (34) having a resiliently compressible surface with a hardness of about 70 to 100 Shore A Durometer contacts the reverse direction roller and is gear driven at a speed proportional to the plate cylinder. A water form roller (38) contacts both the ink receptive oscillating roller and the plate cylinder.
